| 1933 | Born and grew up in Worcester, UK. Father involved in farming and horse training and worked for the Ministry of Agriculture. Mothers family, market gardeners. Went to school in Worcester during the war. No art education at school but did make "desperate attempts" at what he thought was "Modern Art", influenced by analytical cubist works by Picasso and Gris in art encyclopedias. |
| 1950-1952 | Influenced by his father’s involvement in agriculture, he attended the Shropshire Institute of Agriculture where he studied for a National Diploma in Agricultural Engineering. The Agricultural College shared a building with Worcester School of Art. Read the meaning of Art by Sir Herbert Read which helped him to begin to understand the meaning of form, space, movement and line. |
| 1952 – 1954 | national service, which coincided with the Korean War, during which he saw active service as a tank engineer. Traveled in North and South Korea and Japan. |
| 1954 - 1957 | worked and studied part time for A levels and NDD courses. Casual attendance at Worcester College of Art where he met Geoffrey Whiting and spent time with him assisting with filling his kiln. |
| 1957 - 1960 | Attended Bath Academy of Art aged 24. Enthusiastically embraced the unconventional teaching at Bath at that time. He quickly established a strong disposition towards abstraction as a form of painting. Taught by Adrian Heath, Martin Froy, Anthony Fry, Howard Hodgkin, Malcolm Hughes, Philip Sutton, Gillian Ayres, William Scott, Jack Smith, John Earnest and Robyn Denny. In his last year at Bath he was commissioned to make a 15 x 9 foot abstract mosaic for a college in Wiltshire. The first signs of grids and blocks of colour within a grid construction began to appear in his work at this time. |
| 1960-1961 | Won an Italian Government Scholarship in Art to study mosaic in Ravenna. Here he visited the commercial mosaic studios and photographed the building site hoardings which inspired the Pop Art poster collages he went on to make the next year. |
| 1961-1962 | Married fellow Bath Academy of Art student Eve Laurens. Worked part time painting Lambs Navy Rum figures in a studio with Mark Vaux and Quentin Crisp. Part time teaching. Made the Pop Poster collages as a "homage to Pop Art" |
| 1962 | Started work at Croydon College of Art, where he was to teach for the next 8 years. Colleagues at Croydon included John Hoyland, Alan Jones, Bridget Riley, Bruce McLean, David Leveret, Barry Fantoni and Michael Simpson. |
| 1964 – 1966 | Started working on the Op Art paintings, exhibiting with Bridget Riley, Michael Kidner, Geoffrey Steele, Fred Carver and Peter Sedgely at Mc Roberts & Tunnard Gallery |
| 1966 | Commonwealth Scholar (Art and Architecture). Traveled extensively in India. |
| 1967 | Introduced moiré /interferometry to his work, experimenting with line and colour, optical effects and the relationship between art and science. Mediums included resist line drawing and wash over with fast acid dyes. Also worked on Op Art prints at this time. First solo exhibition, University of Sussex. |
| 1968 | Started work on the two colour stripe acrylic paintings, still using moiré and painting on a very large scale. Starts to be influenced by US painters such as Noland, Stella, and Newman. The two colour stripe paintings installed at Match Shed, London. One man show with Angela Flowers, London. |
| 1971 | Invited by Malcolm Hughes to join Matrix, a group of artists including Michael Kidner, Geofrey Steele, John Earnest and Jean Spencer. The Matrix Exhibition opened at the Arnolfini Gallery in 1971 and led to the Sytems Exhibition curated by Nicolas Serota which opened at the Whitechapel gallery in 1972. |
| 1972 | Returned to drawing, making large scale charcoal works on canvas, washed and fixed with cellulose acetate. These were based on the grid and cross, often using the resist line of his earlier optical work |
| 1974 | Included in the British Painting Exhibition at the Hayward gallery |
| 1975 | Was stimulated by the exhibition "Fundamental Painting / Fundamentele Schilderkunst" mounted at the Stedelijk Museum, Amsterdam, The Netherlands and was later included in the Fundamental Painting exhibition at the Air Gallery, London, curated by Rini Dipel of the Stedeliilk Museum. Solo exhibition at the Institute of Contemporary Arts, London. |
| 1975-1991 | In 1977 he moved to Jersey in the Channel Islands. He continued working on charcoal drawings on canvas and paper and showing mainly in Holland, Belgium, Italy, France, Japan and the USA. |
| 1991-1999 | Returned to England. After nearly two decades of working without colour he started what was to become the series of "white paintings" which would be his last works. They were exhibited at the RHOK gallery, Brussels in 1996, at the Retrospective Exhibition of his work at University of Wales School of Art Gallery, Aberystwyth and at Flowers East in 1999 In 1997 his wife Eve was diagnosed with cancer and died within several months. Soon after he was diagnosed with Motor Neuron Disease. Determined to continue working he explored working with specially adapted computer software but was unable to make any progress due to the rapid onset of the disease. He died in February 1999. |
